摘要：

随着物联网的兴起和移动互联网业务种类的日渐丰富，人们对蜂窝移动通信数据传输速率以及服务质量提出了更高的要求。由于能够充分挖掘空间维的自由度，在提高频谱效率的同时获得较好的功率利用率，大规模MIMO系统引起了国内外的广泛关注。大规模MIMO系统配置的大规模天线阵列在带来性能增益的同时也带来了前所未有的挑战，如大规模天线阵列系统下传输方案的设计、急剧增加的系统硬件复杂度和计算复杂度等。首先对大规模MIMO系统下的几种传输方案，如联合空分复用（JSDM）传输方案和大规模多波束空分多址（MB-SDMA）传输方案进行了概述，简略描述了不同传输方案的原理和传输过程，进一步简要介绍了目前正在构建的大规模MIMO原型验证系统Argos和LuMaMi，并展示了不同原型验证系统的整体架构与组件。

Abstract:

With the rise of the internet of things and rapid development of the mobile internet business，higher data rate of service is demanded. Due to the ability of fully exploiting the spatial degree of freedom and obtaining good energy efficiency while improving spectral efficiency，massive MIMO has attracted wide attention worldwide. Many challenges are also brought by large antenna array at the same time of acquiring performance gain. For example，the design of transmission scheme in massive MIMO system，the dramatic increase in the complexity of hardware and the complexity of computation and so on. Firstly，some transmission strategies such as joint spatial division and multiplexing（JSDM）and massive beam-spatial division multiple access（MB-SDMA）in massive MIMO system，including their principles and transmission process were illustrated，then massive MIMO demo systems Argos and LuMaMi were presented，and the overall structure and component of the different demo systems were also provided.

Key words: massive MIMO system, system transmission scheme, demo system
